QNEET-2016-Ph-1166: NEET 2016 Physics - Class 11 NEET-2016-Ph-1166 Solution: The second overtone of an open organ pipe has the same…
The second overtone of an open organ pipe has the same frequency as the first overtone of a closed pipe L metre long. The length of the open pipe will be L 2L L/2 4L
Multiple Choice Options
- A L
- B 2L
- C 2 L _
- D 4L
Step-by-Step Verified Solution
Second overtone of an open organ pipe
(Third harmonic) = 3 _ v 0 _ = 3 _ v 2 L _
First overtone of a closed organ pipe
(Third harmonic) = 3 _ v 0 = 3 _ v 4 L
According to question,
3 v 0 _ = 3 v 0 _ 3 _ v 2 L _ = 3 _ v 4 L
_ L' = 2L
